Understanding Java's Asynchronous Journey

A walk-through of the evolution and explanation of concurrent programming in Java, from the early days of Threads in Java 1 to the StructuredTaskScope in Java 21. Asynchronous programming skills are no longer “nice-to-have”; almost every programming language has it and uses it. Languages like Go and JavaScript (in Node.js) have concurrency baked into their syntax. Java, on the other hand, has concurrency, but it’s not quite as seamless at the syntax level when compared to something like JavaScript. For instance, take a look at how JavaScript handles asynchronous operations. It’s way more compact and arguably easier to write than Java. JavaScript function fetchData () { return new Promise (( resolve , reject ) => { setTimeout (() => { resolve ( 'Data fetched' ); }, 10000 ); }); } fetchData (). then ( data => console . log ( data )); console . log ( 'Prints first' ); // prints before the resolved data Now, this is equivalent in Java.👇 Java public class Example { public static void ...
